IP RATING INGRESS PROTECTION

Ingress protection rating (IP); this relates to the degree of protection the light provides against solid objects and water ingress. IP ratings are relevant to anywhere that moisture is prevalent, such as bathrooms, utility rooms and outdoor environments. Written as IPXX, the first X denotes the level of protection offered from dust; the second X denotes the level of protection offered from moisture. The higher the numbers are, the better the protection will be.
